Definitions
- Ventilation system ventilator of the passenger compartment of a vehicle.
- the invention relates to the automotive industry, and more specifically the devices for injecting air into the passenger compartment, constituting the terminal part of the heating, ventilation and air conditioning systems of the vehicles.
- the air flows injected into the passenger compartment are of two kinds.
- the flows intended to be directed directly on the occupants of the vehicle penetrate into the passenger compartment by fixed or adjustable aerators.
- Flows intended for indirect distribution in the passenger compartment penetrate through soft diffusion grids totally separate from the aerators.
- two different classes of broadcasting means are therefore used.
- the object of the invention is to provide a new type of aerator that can both ensure the two functions of direct and indirect distribution of ventilation air in the passenger compartment more effectively than those already known.
- a- p ⁇ ur obj ⁇ ⁇ ⁇ and an aerator ⁇ of ⁇ ⁇ lîystemê die "ventilation of the interior of a motor vehicle, constituting the end portion a main air duct conveying an upstream air flow, said aerator being provided with diffusion means for converting the upstream air flow into a downstream diffusion air flow, directional means for converting the flow of air upstream air in a directional downstream air flow, and control means for switching from one downstream air flow mode to the other by connecting one or the other of the diffusion means and the directional means to said main air duct, characterized in that it comprises a central duct at least partially coaxial with an annular duct, the two ducts having their upstream ends connected to the main air duct and each having at its downstream end one of said diffusion means and said directional means, and a control ring which can be placed between a first position where its function is to close a connection between the central duct and the
- It may also include means for closing the central duct controlled by the displacement of the ring.
- Said closure means of the central duct may be constituted by at least one flap.
- a cylindrical common wall separates the central duct and the annular duct, said common wall is provided with perforations along one of its circumferences, said ring is inserted around said common wall and carries perforations which can by rotating the ring, to at least one angular position, coming in correspondence with said perforations of the common wall, said ring also being able, by rotation to at least one other angular position, to seal said perforations of the common wall .
- Said diffusion means may comprise one or more perforations formed at the end of said annular duct in the front part of the ring intended to protrude into the passenger compartment of the vehicle when the aerator is mounted in the dashboard.
- said ring constitutes a
- the annennial ⁇ lclear 71l comprises means for ensuring a translation of the ring along of its longitudinal axis simultaneously with its rotation to move the ring from a closed position of the annular conduit to a closed position of the central duct.
- the front portion of the ring may comprise on its periphery a lip which, when the ring is in the maximum recoil position, is intended to come into contact with the outer face of the dashboard to seal the annular duct, when the ring is in an advanced position, its rear end is remote from the outer wall of the aerator so as to allow the passage of at least a portion of the upstream air flow in the annular duct to form the flow of diffusion air, and in this same advanced position, the lip is intended to be moved away from the dashboard so as to define an annular opening through which the flow of diffusion air can enter the passenger compartment.
- Said means making it possible to ensure a translation of the ring simultaneously with its rotation may comprise one or more helical ribs which are inserted in one or corresponding housings formed on a part integral with the outer wall of the aerator.
- Said diffusion means may comprise at least one perforation formed on at least a portion of the outer wall of the aerator, and through which the downstream flow of diffusion air enters the passenger compartment.
- They may then include a flag directing in the passenger compartment the downstream air flow of diffusion out of the perforation.
- Said ring can preferably be maintained in at least one intermediate position between said first and second positions, so as to simultaneously allow the passage of a downstream flow of diffusion air and a directional downstream air flow in the cockpit.
- the aerator according to the invention comprises two coaxial ducts each connected to the main air duct. One carries at its downstream end the direct diffusion means, and the other carries at its downstream end the indirect diffusion means.
- a ring controllable by the user -permetrà-the-EI--aismos choose one of ⁇ ee Fautre "DEIK" typ ⁇ sTdê ⁇ cliffiJsTôn air through the aerator concerned and preferably various compromises between these two types of diffusion.
- the aerator according to the invention is of simple design and is therefore inexpensive to manufacture.
- FIG. 1 represents in longitudinal section a first example of an aerator according to the invention, in a direct diffusion position (FIG. ig .1 a) and in indirect diffusion position (fig.ib);
- FIG. 2 which shows in longitudinal section a second example of aerator according to the invention in the direct diffusion position (fig.2a) and indirect diffusion position (fig.2b);
- FIG. 3 which shows in longitudinal section a third example of aerator according to the invention in direct diffusion position.
- a first example of aerator according to the invention is intended to be embedded in an orifice in the dashboard 1 of the vehicle and to be connected, by its upstream end, in a connection zone 2 to a main air duct (not shown), itself connected to the heating, ventilation and air conditioning system of the vehicle.
- the main air duct brings to the aerator an upstream air flow symbolized by the arrow 3.
- the aerator Downstream of the connection zone 2, the aerator comprises two coaxial conduits of circular sections, separated by a cylindrical common wall 4.
- the central duct 5 is dedicated to the passage of a directional downstream air flow, symbolized by the arrows 6, in the passenger compartment 7 of the vehicle.
- the annular duct 8 is dedicated to the passage of a downstream air flow of diffusion symbolized by the arrows 9.
- the common wall 4 separating the two ducts 5, 8 is provided with spaced perforations 10 located in its upstream portion and arranged according to a circumference of said common wall 4.
- the wall of the ring 12 carries spaced perforations 15 which, when the ring 12 is inserted into the aerator, can come into correspondence with the perforations 10 of the common wall 4 if the ring 12 is turned by the user (or a automatically controlled device) of a suitable angle.
- the upstream air flow 3 has the possibility of passing through the annular duct 8 through the perforations 10, 15, especially if the central duct 5 is closed.
- the rotation of the ring 12 also controls the movement of a series of flaps 16 (central flap) 17, 18 (front flaps).
- the central flap 16 is disposed inside the central duct 5 and can rotate about an axis 19 which, in the example shown, is located substantially on the longitudinal axis of the aerator and is perpendicular thereto.
- the axis 19 is also located downstream of the perforations 10 of the common wall 4.
- the front flaps 17, 18 at the downstream end of the central duct 5 are supported by a ring 21. They can similarly rotate about axes substantially perpendicular to the longitudinal axis of the aerator. When in the maximum open position ( Figure 1a) they do not interfere with the output of the directional air flow 6 and contribute to its orientation. When they are in the closed position (fig.ib) they contribute to the closing of the central duct 5, for example each coming into abutment on the one hand against the periphery of the central duct 5 and / or on the other hand against a side of the other front panel 17, 18 (case shown in Figure 1b).
- the ring 12 and the flaps 16, 17, 18 can, at the request of the user, take one or more intermediate positions, preset or not, or even be able to pass continuously continuously, between the two extreme positions that have have been described and represented. It is thus possible to modulate in a more or less fine manner the respective proportions of downstream directional air 6 and downstream diffusion air 9.
- These intermediate positions could be preset by means of, for example, a notching provided on the periphery of the ring 12.
- FIG. 2 A second example of aerator according to the invention is shown in Figure 2.
- the elements common with the example of Figure 1 are identified by the same reference numerals.
- the lip 24 is located away from the dashboard 1 and thus provides an annular opening 26.
- the upstream air flow 3 has the possibility of entering the annular duct 8 and exit through the opening 26.
- the flaps 16, 17, 18 are all in the closed position (the bearing surfaces 20 on which the central flap 16 abuts are here provided on the ring 12), thus closing the central duct 5. It is therefore the entirety of the upstream air flow 3 which is converted in downstream air flow of diffusion 9.
- one or more intermediate positions between those described and shown may be selectable by the user.
- the ring 12 is combined with a rotation of the ring 12.
- the axis of rotation of the ring 12 can be confused with the longitudinal axis of the aerator, the installation of the aerator in the dashboard 1 does not pose any particular problems.
- the annular duct 8 extends over the entire periphery of the central duct 5, but this characteristic is not mandatory: the annular duct 8 may extend only over a portion of this periphery.
- FIG. 3 The example of aerator according to the invention shown in Figure 3 has this feature. It is comparable, in its general design, to that of Figure 1, in that the ring 12 is inserted around the common wall 4 of the two central ducts 5 and annular 8 and performs during its movements a pure rotation, without translation . It differs in the following points:
- downstream diffusion air stream 9 can escape from the annular duct 8 by a single perforation 27 extending on the periphery of the annular duct 8
- the central flap 16 and the front flaps 17, 18 can be actuated in a synchronized manner by means of rods of such-such-a-action suri'urrd ⁇ s ⁇ wishess " 16, ⁇ ⁇ 7 " 18 " s ⁇ ⁇ repè7c ⁇ T ⁇ on the other.
- a bond spherical rods allows to turn the ring 21 supporting the front flaps 17, 18 around the longitudinal axis of the aerator independently of the central flap 16, so as to orient the directional downstream air flow 6 as the user wishes.
- the rotation of the central flap 16 about the axis 19 when the control ring 12 is actuated can be done by a rack and gear system, moving relative to each other when the actuator is actuated.
- the axis 19 comprises a gear secured to the central flap 16, and the rack is carried by a fixed portion of the aerator.
- the rack is mounted on the control ring.
- the shape of the rack is adapted to the pure rotation (case of FIG. 1) or helicoidal rotation (case of FIG. 2) of the control ring 12.
